(CNN) — The federal government has concluded there’s a new leaker exposing national security documents in the aftermath of surveillance disclosures by former NSA contractor Edward Snowden, U.S. officials tell CNN.

Proof of the newest leak comes from national security documents that formed the basis of a news story published Tuesday by the Intercept, the news site launched by Glenn Greenwald, who also published Snowden’s leaks.

The Intercept article focuses on the growth in U.S. government databases of known or suspected terrorist names during the Obama administration.

The article cites documents prepared by the National Counterterrorism Center dated August 2013, which is after Snowden flew to Russia to avoid U.S. criminal charges.

Greenwald has suggested there was another leaker. In July, he said on Twitter “it seems clear at this point” that there was another. Government officials have been investigating to find out who.

The biggest database, called the Terrorist Identities Datamart Environment, now has 1 million names, a U.S. official confirmed to CNN.

That’s boosted from half that many in the aftermath of the botched attempt by the so-called underwear bomber to blow up a U.S.-bound jetliner on Christmas Day in 2009.

The growth of TIDE, and other more specialized terrorist databases and watchlists, was a result of vulnerabilities exposed in the 2009 underwear plot, government officials said.

The underwear bomber, Umar Farouk Abdulmuttalab, was not on government watchlists that would have prevented him from being allowed to fly to the United States.

In 2012, the National Counterterrorism Center reported that the TIDE database contained 875,000 names. There were about 500,000 in 2009 before the underwear bomb plot.

The Intercept first reported the new TIDE database numbers, along with details of other databases.

One watchlist, the Terrorist Screening Database, which is a subset of the TIDE database, has 680,000 names, only a small number of which are Americans.

The Intercept report said, citing the documents, that 40% of those 680,000 don’t have affiliations to terrorist groups.

U.S. officials familiar with the matter say the claim is incorrect based on a misreading of the documents.

The report said that as of August, 2013, 5,000 names of Americans were on the TSD watchlist. Another 15,800 were on the wider TIDE list.

A smaller subset, 16,000 names, including 1,200 belonging to Americans, are listed as “selectees” who are subject to more intensive screening at airports and border crossings.

According to the Intercept, citing the documents, the cities with the most names on the list are: New York, Dearborn, Michigan; Houston; San Diego; and Chicago. Dearborn is home to one the nation’s biggest concentrations of Arab and Muslim populations.

According to the documents cited by the Intercept, the government has also begun a new effort to collect information and biometric data on U.S. persons in the aftermath of the 2013 Boston Marathon bombings.

The data includes photos from driver’s licenses. That effort likely was spurred by the fact that FBI agents investigating the Boston bombings found existing databases lacking when they tried to match images of the two bombers isolated from surveillance video, according to U.S. officials familiar with the matter.
